Signaling Pathways >> GPCR/G Protein >> Histamine Receptor
Signaling Pathways >> Immunology/Inflammation >> Histamine Receptor
Research Areas >> Inflammation/Immunology

[Target]

Histamine H1-receptor[1]


[In Vitro]

Mebhydrolin is a specific histamine H1-receptor antagonist with minimal sedative properties and comparing it with the effects of chlorpromazine, the archetypical phenothiazine[1]. Mebhydrolin exerts an antihistaminic effect over the period of the ethanol interaction study[2].
